Nuclear cardiology
About 78451: Single-study myocardial SPECT perfusion imaging
Reports one SPECT myocardial perfusion study at rest or stress to assess blood flow to the heart muscle in suspected or known coronary disease.
This service uses a radiopharmaceutical and a gamma camera to create tomographic images of myocardial perfusion for one study, performed at rest or under exercise or pharmacologic stress. Cardiologists, nuclear medicine physicians, and radiologists may interpret the images in hospital or outpatient imaging settings. Clinicians commonly use the study to evaluate suspected or established coronary artery disease and possible ischemia or prior myocardial injury.
Report 78451 for a single rest or stress study; when both rest and stress studies are performed, 78452 is the related SPECT code. Documentation should identify the study condition and support the imaging and interpretation performed. The code has professional and technical components: modifier 26 identifies the interpretation, modifier TC identifies equipment and staff, and no component modifier represents the global service. The cardiovascular diagnostic multiple procedure reduction applies to the technical component.
CMS billing rules for 78451
- Professional and technical components
- Diagnostic test with a professional component (modifier 26, interpretation) and a technical component (modifier TC, equipment and staff); billing without a modifier is the global service.
- Multiple procedures
- Cardiovascular diagnostic multiple procedure reduction applies to the technical component.

78451 billing questions
When is 78451 reported instead of 78452?
Use 78451 for one SPECT myocardial perfusion study at rest or stress. When the service includes both rest and stress studies, compare the documentation with 78452.
Does one study mean one image or one view?
No. The distinction is the number of myocardial perfusion studies, not the number of image slices or views. Document whether the single study was performed at rest or stress.
How should the professional and technical work be billed?
Use modifier 26 for the physician's interpretation and modifier TC for the equipment and staff. Report the global service without either component modifier when one claim includes both portions.
Can the technical component be reduced when other tests are performed?
The cardiovascular diagnostic multiple procedure reduction applies to the technical component of 78451. It does not change the professional component under the CMS rule provided.
What documentation supports 78451?
Document that myocardial perfusion SPECT was performed, whether the single study was at rest or stress, and the physician's interpretation. For stress imaging, identify the stress method used.
Where these rates come from
FeeBase calculates base physician payments from CMS work, practice-expense, and malpractice RVUs, adjusted by each locality’s geographic indices and the applicable conversion factor. Unavailable or separately priced services are labeled rather than assigned a made-up amount.
